Magnet Gear with Two-Axial Magnetic Paths

Journal of the Korean Society for Precision Engineering, 2014
A magnet gear composed of two layers of permanent magnets repeated circumferentially can transmit the power without mechanical contact. In the topology called by the magnet shutter gear known as the most competitive concept among the existing concepts, the number of pole-pairs on the high speed rotor corresponds to that of low speed rotor through ...

A new magnetic gear using permanent magnet

IEEE Transactions on Magnetics, 1987
This paper describes the structure and the performance characteristics of a magnetic gear using SmCo 5 for the permanent magnet. The magnetic gear has a gear ratio of 1/3 and the maximum transmitted torque is 5.5 Nm at the driven magnetic gear. When the rotating speed of the driving magnetic pinion is 2000 rpm, the driven magnetic gear rotates at 2000 ...

Reluctance magnetic gear and flux switching magnetic gear for high speed motor system

2017 IEEE Energy Conversion Congress and Exposition (ECCE), 2017
In the industrial field, the drive system integrated the high speed motor and the gear is required to effectively utilize the limited space. However, mechanical gears often require their lubrication and cooling, they generate whilst noise and vibration. To overcome these problems, the magnetic gears have been expected. Magnetic gears achieve the system

Gearing ratios of a magnetic gear for marine applications

2009 IEEE Electric Ship Technologies Symposium, 2009
Marine propulsion systems have become increasingly electromechanical in recent years. Proposed systems show increasing torque density in an effort to reduce volume and weight. A magnetic gear is proposed to reduce the size of the propulsion motor and achieve similar torque amplification provided by a mechanical gearbox, without the maintenance and ...

Gearing ratios of a magnetic gear for wind turbines

2009 IEEE International Electric Machines and Drives Conference, 2009
The wind turbine industry is growing at an incredible rate as numerous governments demand an increase in renewable energy generation capacity. The great multitude of turbines on windfarms throughout the world range from ones which are controlled mechanically with gears to ones which are controlled with power electronics and no gears. A drivetrain for a

Embedded PM magnetic-geared generator

International Journal of Applied Electromagnetics and Mechanics, 2014
This paper proposes a new magnetic-geared generator, which has a novel permanent magnet arrangement whereby the permanent magnets are embedded into the high-speed rotor and the stator slots, for direct-drive wind power generation systems. The operational principle is described and the performance is verified by using finite element analysis.

A continuously variable magnetic gear

2013 International Electric Machines & Drives Conference, 2013
A magnetic gear is presented that is capable of continuously varying the gear ratio in order to enable constant magnified output speed to be generated from variable input speed. A flux focusing (spoke type) inner rotor is utilized and the performance of the device is assessed when using three different stator winding configurations.
